Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: comprises a frame 1, an air suction seeding box 2, a furrow opener 4 and a high-speed fan,

a plurality of groups of air suction sowing boxes 2 are arranged on the frame 1, a seed sowing pipe 3 is arranged at the bottom of each air suction sowing box 2, the bottom end of each seed sowing pipe 3 is fixedly connected with a furrow opener 4, and soil covering wheels 5 are arranged on two sides of the tail end of each furrow opener 4;

the utility model discloses a seed storage bin, including the seed metering dish, the seed metering dish is provided with the seed metering case 2, be provided with case shell 7 in the case shell 7, seed metering dish 8 rear end is provided with sucking disc 9, and evenly is provided with on the sucking disc 9 and inhale the hole 10, sucking disc 9 rear end is provided with vacuum chamber 11, and this vacuum chamber 11 is connected with outside negative pressure breathing pipe 6, seed metering dish 8 front end both sides are provided with respectively and scrape kind ware 12 and seeding dish 13, and scrape kind ware 12 and seeding dish 13 on all are provided with the baffle, and this baffle makes its interior formation of seed storage bin 14 with case shell 7 cooperation.
